Sorry I was referring to the boost you get from having ram integrated into the chip vis-à-vis apple’s M-line of processors.
Having replaceable ram is not really a marketable feature these days.

It is true that it's not currently feasible to have socketed memory in a laptop offering 8+ memory channels to enable 200GB/sec+ bandwidth, but you can absolutely get the same (or greater!) memory speeds as an M-series CPU from an x86 desktop workstation.
If Intel/AMD wanted to prioritize memory bandwidth, they could probably work with JEDEC or another industry org to develop a new standard for socketed memory with multiple channels per socket, to enable the kind of speeds that Apple offers. The fact that they haven't (to my knowledge) indicates to me that they don't see it as a big enough priority or benefit.
Thanks, I did not know this! I would have honestly have bought into Apple's marketing that the soldering is what allows them to make it more integrated and faster
The CAMM2/LPCAMM2 standard is a new way of having replaceable memory which takes up less physical space and is faster, if you're interested. There are a few laptops (and desktops) out there using it already. It still only supports dual-channel memory, though.
As I said originally, my suspicion is that "200GB/s+ memory bandwidth!" might be good marketing copy and make for good synthetic benchmark results, but just isn't actually that beneficial for the average computer user in the real world. This could be why you don't see other computer manufacturers pursuing it, at least not in laptops.
A week ago, I helped a family member select a laptop. One of the criteria is either sufficient RAM to begin with (16GB puts them into a price class above what they actually need for other specs) or upgradeable RAM. It's definitely something I look at for myself and for those around me also -- more so than in the past because nowadays it has become a problem...
